BolderBoulder

For the BOLDERBoulder 10K, which traditionally takes place on Memorial Day (May 31, 2027), the event organizers emphasize planning ahead due to heavy traffic and significant road closures [1, 2]. ### **Recommended Arrival Time** * **Plan Early:** Organizers strongly recommend arriving well in advance of your start time to account for heavy traffic and potential 45-minute delays when exiting parking lots after the event [1]. * **Parking Availability:** Parking lots typically open three hours prior to the start of the event and operate on a first-come, first-served basis [1]. ### **Transportation Options** * **Public Transit:** Note that **RTD does not provide a "RunRide" service** for the event [2]. You should plan for alternative transportation. * **Biking:** Biking is highly encouraged as both the start and finish areas are near the Boulder Creek Path [1, 2]. * **Google Bike Parking:** Located at 30th Street and Pearl Street, this facility opens at 6:00 a.m. It is first-come, first-served, and you must bring your own lock [1, 2]. * *Note:* Paths along 30th Street are typically closed from 5:00 a.m. to 9:30 a.m., so use 29th Street as an alternative [2]. * **Runner Drop-Off Zones:** There are designated drop-off locations near the start line: 1. **Arapahoe Ave:** Westbound, right lane between 38th and 30th Street [1, 2]. 2. **28th Street:** Northbound frontage road (enter at Pennsylvania, just north of Colorado) [1, 2]. * **Rideshare:** De
